Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 103672-2 is determined by the following critical parameters: connector type (Header), contact type (Male Pin), mating pitch (0.100" / 2.54mm), number of positions (3), number of rows (1), mounting type (Through Hole, Right Angle), shrouding configuration (Shrouded - 4 Wall), termination method (Solder), contact shape (Square), and material flammability rating (UL94 V-0). All identified substitute parts maintain these core electrical and mechanical characteristics.

Secondary parameters that may vary between the main part and substitutes include contact material (Brass versus Phosphor Bronze), contact finish composition (Tin-Lead versus Tin versus Gold), contact finish thickness, insulation material (Thermoplastic versus Polyester Glass Filled), operating temperature range, voltage rating, and compliance certifications (RoHS status, REACH status). These variations do not preclude substitution but must be evaluated against specific application requirements.

The substitute parts are grouped as follows:

Direct Equivalent: TE Connectivity 5-103672-2 maintains identical electrical and mechanical specifications with the primary difference being contact finish composition (Tin versus Tin-Lead) and RoHS3 compliance status.

Similar Alternatives: Molex 0705530002 and Molex 0705530037 provide functionally equivalent headers with the same mating pitch, position count, mounting configuration, and shrouding. These parts differ in contact material (Phosphor Bronze versus Brass), contact finish specifications, insulation material composition, operating temperature range, and voltage rating.

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 5-103672-2 is the primary direct equivalent for TE Connectivity 103672-2. Both parts maintain identical mechanical dimensions, electrical ratings, and operating temperature specifications. The 5-103672-2 variant features Tin contact finish instead of Tin-Lead and carries ROHS3 compliance certification, making it suitable for applications subject to RoHS3 regulatory requirements. Selection of the 5-103672-2 is appropriate when RoHS3 compliance is mandated or when Tin-only contact finish is preferred over Tin-Lead composition.

Molex 0705530002 and Molex 0705530037 provide functionally equivalent alternatives from a different manufacturer. Both Molex parts maintain the same mating pitch, position count, mounting configuration, and shrouding specification. Key differences include Phosphor Bronze contact material (versus Brass), operating temperature range limited to -40°C to 105°C (versus -65°C to 105°C), and specified voltage rating of 250V. The Molex 0705530002 features Gold mating contact finish with minimal thickness (15.0µin), while the 0705530037 features Tin mating contact finish with increased thickness (150.0µin). Both Molex parts are ROHS3 compliant and REACH unaffected.

Selection of Molex alternatives is appropriate when supply availability of TE Connectivity parts is constrained, when the extended low-temperature operating range of -65°C is not required, or when the specified 250V voltage rating is beneficial for the application. The Molex 0705530037 with thicker Tin finish may be preferred for applications requiring enhanced corrosion resistance or contact durability.

All substitute parts maintain UL94 V-0 flammability rating and unlimited moisture sensitivity level (MSL 1), ensuring compatibility with standard manufacturing and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can TE Connectivity 5-103672-2 be used as a direct replacement for TE Connectivity 103672-2?

A: Yes. The 5-103672-2 maintains identical mechanical dimensions, electrical ratings, and operating temperature range. The primary difference is contact finish composition (Tin versus Tin-Lead) and RoHS3 compliance status. Both parts are functionally interchangeable in applications where Tin contact finish is acceptable.

Q: What are the key differences between TE Connectivity and Molex substitute options?

A: TE Connectivity 5-103672-2 is a direct equivalent with identical specifications. Molex 0705530002 and 0705530037 are similar alternatives that differ in contact material (Phosphor Bronze versus Brass), operating temperature range (-40°C to 105°C versus -65°C to 105°C), contact finish specifications, and insulation material (Polyester Glass Filled versus Thermoplastic). All parts maintain the same mating pitch, position count, and mounting configuration.

Q: Should I select Molex 0705530002 or Molex 0705530037?

A: Both Molex parts are functionally equivalent. The 0705530002 features Gold mating contact finish with 15.0µin thickness, suitable for applications requiring minimal contact resistance. The 0705530037 features Tin mating contact finish with 150.0µin thickness, suitable for applications requiring enhanced corrosion resistance. Selection depends on specific contact performance requirements.

Q: Are all substitute parts RoHS3 compliant?

A: TE Connectivity 103672-2 is marked as "Not applicable" for RoHS status. TE Connectivity 5-103672-2, Molex 0705530002, and Molex 0705530037 are all ROHS3 compliant. If RoHS3 compliance is required, select from the three compliant alternatives.

Q: What is the operating temperature limitation when using Molex substitutes?

A: Molex 0705530002 and 0705530037 operate across -40°C to 105°C, compared to the TE Connectivity 103672-2 range of -65°C to 105°C. If the application requires operation below -40°C, TE Connectivity parts must be selected.

Q: Do all substitute parts have the same current rating?

A: TE Connectivity 103672-2 and 5-103672-2 are rated for 3A continuous current. Molex 0705530002 and 0705530037 do not specify a current rating in the provided data. Verify Molex current rating specifications with the manufacturer if current capacity is a critical design parameter.

Q: What voltage rating should I consider for this application?

A: TE Connectivity 103672-2 and 5-103672-2 do not specify a voltage rating. Molex 0705530002 and 0705530037 are rated for 250V. If voltage rating is a design requirement, Molex alternatives provide explicit 250V specification.

Q: Are there packaging differences between these parts?

A: All four parts are supplied in Tube packaging. No packaging format differences exist among the main part and substitutes.

Q: Can I mix TE Connectivity and Molex connectors in the same assembly?

A: All parts maintain identical mating pitch (0.100" / 2.54mm), position count (3), and shrouding configuration (Shrouded - 4 Wall). Mechanical compatibility is ensured. Verify contact finish and material compatibility with mating connector specifications before mixing manufacturers in the same assembly.
