Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 770602-5 is determined by strict adherence to the following critical parameters: connector type (receptacle), contact type (female socket), number of positions (5), pitch (0.100" / 2.54mm), number of rows (1), mounting type (free hanging in-line), contact termination (crimp), and fastening type (locking ramp). All substitute parts listed maintain these core specifications, ensuring mechanical and electrical compatibility within the same application envelope.

Substitute parts are grouped into two categories:

Direct Equivalents (TE Connectivity CST-100 Series): Parts 1375820-5 and 102241-3 are direct parametric equivalents from TE Connectivity, maintaining identical electrical and mechanical specifications while offering active product status and improved availability.

Cross-Manufacturer Equivalents (Molex): Parts 0050579505 and 0901560145 are parametric equivalents from Molex, maintaining identical pitch, position count, mounting configuration, and termination method. Part 0022011052 is a similar alternative with 0.098" (2.50mm) pitch, representing a near-pitch alternative for applications permitting minor dimensional variance.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (TE Connectivity): Parts 1375820-5 and 102241-3 are recommended as primary substitutes due to manufacturer continuity with TE Connectivity. Both parts maintain identical electrical and mechanical specifications to the 770602-5 while offering active product status. Part 1375820-5 (CST-100 II series, white color) provides the most direct functional replacement with RoHS compliance. Part 102241-3 (AMPMODU Mod IV series, black color) offers ROHS3 compliance and extended operating temperature range (-65°C to 105°C).

Secondary Substitutes (Molex): Parts 0050579505 and 0901560145 are parametric equivalents from Molex, maintaining identical pitch, position count, and termination specifications. Both are ROHS3 compliant with active product status. Part 0901560145 (C-Grid III 90156 series) features polyphenylene oxide insulation and operates across -55°C to 105°C. Part 0050579505 (SL 70066 series) features polyester glass-filled insulation and operates across -40°C to 105°C.

Alternative Substitute (Molex): Part 0022011052 (KK250, 5051 series) operates at 0.098" (2.50mm) pitch, representing a near-pitch alternative. This part is suitable only for applications where minor pitch variance is acceptable. It features polyamide nylon 6/6 insulation, operates across -40°C to 105°C, and includes a polarizing key feature. ROHS3 compliance and REACH unaffected status are confirmed.

All substitute parts maintain MSL 1 (Unlimited) moisture sensitivity classification, ensuring compatibility with standard storage and handling protocols.

Frequently Asked Questions (FAQ)

Q: Can the 770602-5 be directly replaced with 1375820-5 or 102241-3?

A: Yes. Both 1375820-5 and 102241-3 are direct parametric equivalents maintaining identical connector type, contact type, position count, pitch, mounting configuration, contact termination, and fastening type. The primary differences are color (white for 1375820-5, black for 102241-3) and series designation (CST-100 II and AMPMODU Mod IV respectively). Both are active products with improved availability compared to the obsolete 770602-5.

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

A: TE Connectivity substitutes (1375820-5 and 102241-3) maintain manufacturer continuity and identical series-level specifications. Molex substitutes (0050579505 and 0901560145) are parametric equivalents with identical electrical and mechanical interface specifications but differ in insulation material composition and operating temperature ranges. All maintain identical pitch, position count, and termination methods.

Q: Is the Molex 0022011052 a suitable substitute?

A: Part 0022011052 operates at 0.098" (2.50mm) pitch compared to the 0.100" (2.54mm) pitch of the 770602-5. This represents a near-pitch alternative suitable only for applications where minor dimensional variance is acceptable. The part maintains identical position count, mounting type, and termination method, but the pitch difference may affect mechanical fit in existing connector assemblies.

Q: What compliance certifications should be considered for new designs?

A: All active substitute parts are ROHS3 compliant, meeting current regulatory requirements. The 770602-5 (obsolete) does not specify RoHS status. For new designs, 1375820-5, 102241-3, 0050579505, 0901560145, and 0022011052 all provide ROHS3 compliance. REACH status varies: TE Connectivity parts show vendor undefined status, while Molex parts are REACH unaffected.

Q: Are contacts included with these connector housings?

A: No. All parts listed, including the main part 770602-5 and all substitutes, are connector housings only. Contacts are not included and must be sourced separately according to application requirements.

Q: What is the significance of the locking ramp fastening type?

A: The locking ramp fastening type provides mechanical retention and alignment during mating operations. All primary and secondary substitutes (1375820-5, 102241-3, 0050579505, 0901560145) maintain this fastening specification. Part 0022011052 does not specify fastening type, representing a potential compatibility consideration for applications requiring positive mechanical locking.

Q: Can these parts be used interchangeably in existing assemblies?

A: Parts 1375820-5 and 102241-3 are direct mechanical and electrical equivalents and can be used interchangeably with the 770602-5 in existing assemblies. Molex parts 0050579505 and 0901560145 are parametric equivalents suitable for new designs or applications where cross-manufacturer compatibility is acceptable. Part 0022011052 requires design review due to pitch variance.
