Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connector housings is determined by strict equivalence across the following critical parameters: connector type (receptacle), contact type (female socket), number of positions (6), pitch specification (0.156" / 3.96mm), number of rows (1), mounting configuration (free hanging in-line), and contact termination method (crimp). These parameters define the mechanical and electrical interface compatibility with mating connectors and contact systems.

The substitute part TE Connectivity AMP Connectors 640251-6 satisfies all mandatory substitution criteria. Both parts maintain identical specifications for connector type, contact type, position count, pitch, row configuration, mounting type, and termination method. Operating temperature ranges differ slightly (-55°C to 105°C versus -65°C to 105°C), with the substitute part maintaining the upper limit while narrowing the lower temperature specification. Both parts carry RoHS compliance and MSL 1 ratings, confirming environmental and regulatory equivalence.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 640251-6 serves as a direct functional equivalent to the obsolete 87025-2 housing. Both parts maintain identical mechanical and electrical interface specifications across all critical substitution parameters. The 640251-6 is classified as active product status, ensuring ongoing availability and supply chain continuity.

Selection of the 640251-6 substitute is appropriate for applications where the operating temperature minimum of -55°C satisfies system requirements. For applications requiring operation below -55°C, the original -65°C minimum specification of the 87025-2 cannot be matched by this substitute, and alternative solutions must be evaluated.

Both parts carry RoHS compliance and MSL 1 ratings, confirming equivalent environmental and regulatory standing. The substitute part is available in bulk packaging with significantly higher inventory levels (18,875 pieces versus 677 pieces), supporting production scalability and supply security.

Frequently Asked Questions (FAQ)

Q: Can the 640251-6 directly replace the 87025-2 in existing designs?

A: The 640251-6 provides direct mechanical and electrical interface compatibility with the 87025-2. Both parts share identical connector type, contact type, position count, pitch, mounting configuration, and termination method. Compatibility is confirmed for applications operating within the -55°C to 105°C temperature range.

Q: What is the primary difference between these two parts?

A: The main differences are product status and operating temperature range. The 87025-2 is obsolete with a -65°C to 105°C operating range, while the 640251-6 is active production with a -55°C to 105°C range. The 640251-6 also uses polyamide (PA) nylon insulation material compared to the thermoplastic material of the 87025-2.

Q: Are the insulation materials functionally equivalent?

A: Both insulation materials are specified in the provided parameters. The 87025-2 uses thermoplastic insulation, while the 640251-6 uses polyamide (PA) nylon. Both materials support the identical operating temperature range upper limit of 105°C and carry MSL 1 ratings.

Q: What packaging differences exist between these parts?

A: The 87025-2 is supplied without specified packaging designation, while the 640251-6 is supplied in bulk packaging. This difference affects inventory management and order quantities but does not impact functional compatibility.

Q: Are both parts RoHS compliant?

A: Yes, both the 87025-2 and 640251-6 are RoHS compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, confirming equivalent environmental and regulatory compliance.

Q: Why is the 87025-2 classified as obsolete?

A: The 87025-2 is part of the AMPMODU Mod I series, which has been superseded by active product lines such as the SL-156 series represented by the 640251-6. Obsolete classification indicates that the manufacturer has discontinued production in favor of newer equivalent designs.

Q: Can I use the 640251-6 in applications requiring -65°C operation?

A: No. The 640251-6 operating temperature minimum is -55°C. Applications requiring -65°C operation cannot use this substitute. Alternative components with extended low-temperature specifications must be identified.

Q: Are the contact specifications identical between these parts?

A: Both parts specify crimp-type female socket contacts for 6-position housings. The parts are noted as "Contacts Not Included," indicating that contacts are procured separately and must be compatible with the 0.156" (3.96mm) pitch specification.
