TE Connectivity 1-87977-8 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1-87977-8 is a 40-position rectangular connector receptacle housing designed for 0.100" (2.54mm) pitch applications. This component belongs to the AMPMODU Mod IV series and features a female socket contact configuration with crimp termination. The part is classified as Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts are identified when equivalent rectangular connector housings share identical electrical and mechanical specifications, including connector type, contact configuration, position count, pitch, row spacing, mounting method, and contact termination. Alternative sources become necessary due to inventory availability, supply chain considerations, or specific compliance requirements across different manufacturing regions.

Engineering Selection Recommendations

Primary Equivalent: TE Connectivity 1-104482-8

The TE Connectivity 1-104482-8 represents the closest parametric equivalent, sharing the same manufacturer and AMPMODU series lineage. This part maintains identical electrical and mechanical specifications while offering an extended operating temperature range (-65°C ~ 125°C versus -65°C ~ 105°C). RoHS compliance is confirmed, and inventory availability is higher at 2625 pieces. This part is suitable for direct substitution in applications where the extended upper temperature limit provides operational margin.

Secondary Equivalents: Molex 0901430040 and 0022566407

Both Molex rectangular connectors meet all mandatory parametric requirements. The 0901430040 (C-Grid III 90143 series) offers the highest inventory availability at 4798 pieces and maintains the -55°C ~ 105°C operating range. The 0022566407 (SL 70450 series) provides ROHS3 compliance matching the original part specification. Both are suitable for applications requiring alternative manufacturer sourcing.

Alternative Sources: Amphenol ICC (FCI) and Omron

The Amphenol ICC 65043-017LF and 65239-020LF both satisfy core parametric requirements. The 65239-020LF offers extended temperature capability (-65°C ~ 125°C) but features blue housing coloration. The Omron XG5N-401 provides the highest inventory level at 10400 pieces with confirmed RoHS compliance and polybutylene terephthalate insulation material.

Compliance Considerations

All identified substitutes maintain Moisture Sensitivity Level 1 (Unlimited) rating. RoHS compliance is confirmed across all alternatives. Selection should account for specific application temperature requirements, insulation material compatibility with operating environment, and color coding requirements for assembly or identification purposes.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1-87977-8 be directly replaced with the TE Connectivity 1-104482-8?

A: Yes. Both parts share identical connector type, contact configuration, position count, pitch, row spacing, mounting method, and termination type. The 1-104482-8 features an extended operating temperature range (-65°C ~ 125°C) and higher inventory availability. Direct substitution is supported for all applications within the original part's temperature specification.

Q: What is the primary difference between the Molex 0901430040 and 0022566407?

A: Both parts meet identical parametric requirements for connector type, positions, pitch, and mounting configuration. The 0901430040 uses polyphenylene oxide (PPO) insulation material with -55°C ~ 105°C operating range and higher inventory (4798 pieces). The 0022566407 uses polyester glass-filled insulation with -40°C ~ 105°C operating range and ROHS3 compliance. Selection depends on temperature requirements and insulation material compatibility.

Q: Why does the Amphenol ICC 65239-020LF have blue housing while others are black?

A: Housing color is a cosmetic and identification feature that does not affect electrical or mechanical compatibility. The blue color is a series characteristic of the DUBOX™ and MezzSelect™ product lines. Substitution is valid when color coding is not a functional requirement for assembly or system identification.

Q: Is the Omron XG5N-401 suitable for high-volume applications?

A: Yes. The XG5N-401 maintains the highest inventory availability at 10400 pieces and meets all parametric requirements for the 40-position, 2.54mm pitch receptacle configuration. RoHS compliance and polybutylene terephthalate insulation material are confirmed. This part is suitable for high-volume production requirements.

Q: What packaging format differences exist among the substitute parts?

A: The TE Connectivity 1-87977-8 and most substitutes are supplied in bulk packaging. The Omron XG5N-401 is supplied in tube packaging. Packaging format does not affect component functionality or electrical performance. Selection should account for assembly line handling requirements and inventory management procedures.

Q: Can substitutes be mixed within a single assembly?

A: All identified substitutes meet identical parametric specifications for connector type, contact configuration, position count, pitch, and mounting method. Mixing substitutes within a single assembly is supported from an electrical and mechanical standpoint. However, assembly procedures, tooling compatibility, and quality control protocols should be evaluated for each specific application.

Q: What operating temperature range should be selected for critical applications?

A: The original TE Connectivity 1-87977-8 operates from -65°C ~ 105°C. Substitutes offering extended ranges include the TE Connectivity 1-104482-8 (-65°C ~ 125°C) and Amphenol ICC 65239-020LF (-65°C ~ 125°C). Selection should be based on documented application temperature requirements. Parts with narrower ranges (such as Molex 0022566407 at -40°C ~ 105°C) are suitable only when application temperatures remain within specified limits.

Q: Are all substitutes RoHS compliant?

A: Yes. All identified substitute parts maintain RoHS compliance. The original part is ROHS3 compliant. Substitute parts carry either ROHS3 or RoHS compliance designations. All parts meet regulatory requirements for hazardous substance restrictions.
