TE Connectivity 103672-7 Rectangular Connector Header Equivalent & Substitute Parts

Part Overview

The TE Connectivity 103672-7 is an active-status rectangular connector header designed for through-hole, right-angle board-to-board or cable applications. This 8-position, single-row connector operates at 3A current rating across a temperature range of -65°C to 105°C. The connector features shrouded 4-wall construction with solder termination and latch holder fastening, making it suitable for automotive, general purpose, medical, and telecommunications applications. Equivalent and substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when specific packaging, compliance, or material requirements necessitate component substitution.

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 103672-7 is determined by strict equivalence across the following critical parameters: connector type (header), contact type (male pin), number of positions (8), number of rows (1), mating pitch (0.100"/2.54mm), mounting type (through hole, right angle), shrouding configuration (shrouded 4-wall), termination method (solder), and fastening type (latch holder). All identified substitute parts maintain these core electrical and mechanical specifications.

The substitute parts are grouped into two categories:

Direct Manufacturer Equivalent (TE Connectivity 5-103672-7): Identical electrical and mechanical specifications with variation in packaging format (bulk versus tube) and contact finish composition (tin versus tin-lead). This part maintains full compatibility with the original specification.

Similar Manufacturer Alternative (Molex 0705530007): Functionally equivalent across primary connector parameters with documented variations in contact length mating (0.240" versus 0.230"), insulation height (0.215" versus 0.200"), contact material (phosphor bronze versus brass), contact finish (gold versus tin-lead), and insulation material composition (polyester glass-filled versus thermoplastic). Operating temperature range differs (-40°C to 105°C versus -65°C to 105°C). This part is suitable for applications where the specified parameter variations are acceptable.

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 5-103672-7 is the primary direct equivalent for applications requiring identical electrical and mechanical performance to the 103672-7. This part maintains all core specifications including operating temperature range (-65°C to 105°C), contact dimensions, and shrouding configuration. The primary distinction is packaging format (bulk versus tube) and RoHS compliance status (RoHS Compliant versus Not applicable). Selection of this part is appropriate when bulk packaging is acceptable and RoHS compliance is required.

Molex 0705530007 is a functionally equivalent alternative suitable for applications where the documented parameter variations are acceptable. This part is appropriate when: (1) the minimum operating temperature requirement does not extend below -40°C, (2) the increased contact length mating (0.240" versus 0.230") and insulation height (0.215" versus 0.200") are compatible with board layout and mating receptacle specifications, (3) phosphor bronze contact material and gold mating finish are acceptable for the application, and (4) polyester glass-filled insulation material meets environmental and mechanical requirements. This part carries ROHS3 Compliant status and REACH Unaffected designation.

All three parts maintain UL94 V-0 flammability rating, latch holder fastening, and solder termination. Selection should be based on packaging requirements, compliance certifications, and tolerance of the documented mechanical and material variations.

Frequently Asked Questions (FAQ)

Q: Can TE Connectivity 5-103672-7 be used as a direct replacement for 103672-7?

A: Yes. The 5-103672-7 maintains identical electrical and mechanical specifications including connector type, contact configuration, mating pitch, mounting orientation, shrouding, termination method, and operating temperature range. The parts differ only in packaging format (bulk versus tube) and RoHS compliance designation. Substitution is valid when bulk packaging is acceptable.

Q: What are the key differences between TE Connectivity 103672-7 and Molex 0705530007?

A: The parts share identical connector type, contact type, position count, row configuration, mating pitch, mounting type, shrouding, termination, and fastening specifications. Documented differences include: contact length mating (0.230" versus 0.240"), insulation height (0.200" versus 0.215"), contact material (brass versus phosphor bronze), contact finish (tin-lead versus gold), insulation material (thermoplastic versus polyester glass-filled), and operating temperature minimum (-65°C versus -40°C). The Molex part carries a 250V voltage rating specification.

Q: Is the Molex 0705530007 suitable for applications requiring -65°C minimum operating temperature?

A: No. The Molex 0705530007 specifies an operating temperature range of -40°C to 105°C. Applications requiring operation at -65°C must use TE Connectivity 103672-7 or 5-103672-7, which specify -65°C to 105°C.

Q: What is the significance of the contact finish differences between these parts?

A: The TE Connectivity 103672-7 features tin-lead mating contact finish at 100.0µin thickness. The 5-103672-7 uses tin mating finish at equivalent thickness. The Molex 0705530007 uses gold mating finish at 15.0µin thickness. Contact finish affects corrosion resistance, contact resistance, and solderability. Selection should align with mating receptacle specifications and environmental exposure conditions.

Q: Are all three parts suitable for automotive applications?

A: Yes. All three parts list automotive applications in their specifications. However, application-specific requirements regarding operating temperature range, compliance certifications, and material specifications must be verified against design requirements.

Q: What packaging options are available?

A: TE Connectivity 103672-7 is supplied in tube packaging. TE Connectivity 5-103672-7 is supplied in bulk packaging. Molex 0705530007 is supplied in tube packaging. Packaging selection affects inventory management, handling, and cost considerations.

Q: Do all parts meet UL94 V-0 flammability requirements?

A: Yes. All three parts carry UL94 V-0 material flammability rating, meeting flame retardancy requirements for general industrial and consumer applications.

Q: What is the difference in contact material between the parts?

A: TE Connectivity 103672-7 and 5-103672-7 use brass contact material. Molex 0705530007 uses phosphor bronze contact material. Phosphor bronze provides enhanced spring properties and wear resistance compared to brass. Material selection should align with mating force requirements and contact durability specifications.
