TE Connectivity 1-87233-1 Rectangular Connector Header Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1-87233-1 is a right-angle rectangular connector header designed for through-hole mounting applications. This component features 11 positions at 0.100" (2.54mm) pitch and is part of the AMPMODU Mod II series. The part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement continuity. The connector accommodates board-to-board or cable interconnection with solder termination and push-pull fastening.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 1-87233-1 is determined by the following critical parameters:

Primary Matching Criteria:

• Connector type: Header with male pin contacts
• Number of positions: 11
• Pitch: 0.100" (2.54mm)
• Mounting configuration: Through-hole, right-angle orientation
• Termination method: Solder
• Fastening mechanism: Push-pull
• Contact geometry: Square shape
• Shrouding: Unshrouded
• Flammability compliance: UL94 V-0

Secondary Compatibility Factors:

• Insulation material compatibility with board assembly processes
• Contact finish and material composition
• Physical dimensions (insulation height, contact lengths)
• Moisture sensitivity classification

The Molex 0901210131 and Molex 0901210771 satisfy all primary matching criteria. Both are active-status C-Grid III 90121 series headers with identical position count, pitch, mounting type, and termination method. Differences in contact finish, contact material, and insulation material composition are secondary considerations that do not prevent functional substitution in applications where the TE Connectivity part was originally specified.

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 1-87233-1 Obsolescence Status: The TE Connectivity 1-87233-1 is classified as obsolete. Molex 0901210131 and Molex 0901210771 are both active-status products within the C-Grid III 90121 series, providing long-term availability and supply chain continuity.

Compliance and Certification: All three connectors meet UL94 V-0 flammability requirements and carry MSL 1 (Unlimited) moisture sensitivity classification. Both Molex alternatives are RoHS3 compliant and REACH unaffected, supporting modern regulatory requirements.

Physical and Electrical Compatibility: The Molex substitutes maintain identical pitch (0.100"), position count (11), mounting orientation (through-hole right-angle), and termination method (solder). Contact length variations are minor (mating contact: 0.318" vs. 0.266"; post contact: 0.110" vs. 0.114") and insulation height differences are negligible (0.138" vs. 0.142"), presenting no functional impediment in standard board-to-board applications.

Contact Finish Considerations: The TE Connectivity 1-87233-1 features gold-plated contacts (15.0µin thickness). Molex 0901210131 uses tin finish (118.1µin thickness), while Molex 0901210771 matches the gold finish specification (15.0µin thickness). For applications requiring gold contact compatibility, Molex 0901210771 is the preferred substitute.

Material Composition: The TE Connectivity part uses phosphor bronze contacts with thermoplastic insulation. Molex alternatives employ brass contacts with polyester glass-filled insulation. Both material systems are compatible with standard PCB assembly processes and provide equivalent electrical performance in the specified current rating range.

Frequently Asked Questions (FAQ)

Q: Can Molex 0901210131 and Molex 0901210771 be used interchangeably with the TE Connectivity 1-87233-1?

A: Both Molex parts are functionally equivalent substitutes. They share identical connector type, position count, pitch, mounting configuration, and termination method. Selection between them depends on contact finish requirements. Molex 0901210771 matches the gold-plated contact specification of the original part, while Molex 0901210131 uses tin-plated contacts.

Q: What are the key differences between the two Molex alternatives?

A: The primary difference is contact finish. Molex 0901210131 features tin-plated mating and post contacts (118.1µin thickness). Molex 0901210771 has gold-plated mating contacts (15.0µin thickness) matching the original TE Connectivity part, with tin-plated post contacts. Both use identical brass contact material and polyester glass-filled insulation. Packaging differs: 0901210131 is supplied in trays, while 0901210771 is supplied in bulk.

Q: Are there dimensional compatibility concerns when substituting these parts?

A: Minor dimensional variations exist. The mating contact length differs by 0.052" (1.33mm), and insulation height differs by 0.004" (0.10mm). These variations are within standard PCB design tolerances and do not affect mating with standard 0.100" pitch receptacles or cable connectors.

Q: Do the Molex substitutes meet the same regulatory and compliance standards?

A: Yes. Both Molex parts are UL94 V-0 rated, carry MSL 1 (Unlimited) classification, and are RoHS3 compliant and REACH unaffected. All three connectors share the same ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

Q: Why is the TE Connectivity 1-87233-1 listed as obsolete?

A: The AMPMODU Mod II series has been discontinued by TE Connectivity. The Molex C-Grid III 90121 series provides active-status alternatives with equivalent electrical and mechanical specifications, ensuring continued availability for new designs and legacy system support.

Q: What is the significance of the "breakaway" designation on the Molex parts?

A: The breakaway feature allows individual connector positions to be separated from the header strip if required. This does not affect compatibility with standard mating connectors and provides additional design flexibility for applications requiring partial connector configurations.

Q: How do the current ratings compare?

A: The TE Connectivity 1-87233-1 specifies a 3A current rating per contact. The Molex substitutes do not provide explicit current rating specifications in the available data. Applications requiring confirmation of current-carrying capacity should reference the detailed Molex product datasheets or contact the manufacturer directly.
