Part Overview

The TE Connectivity AMP Connectors 770602-4 is a 4-position rectangular connector receptacle housing with 0.100" (2.54mm) pitch, designed for free-hanging in-line mounting applications. This component belongs to the CST-100 series and features crimp contact termination with locking ramp fastening. The part is classified as obsolete, necessitating identification of active equivalent and substitute components for ongoing design and procurement requirements. Equivalent parts maintain identical or compatible electrical and mechanical parameters, while substitute parts offer functional alternatives with minor parameter variations.

Substitute Part Grouping Explanation

Substitution of the 770602-4 is determined by alignment with the following critical parameters: connector type (receptacle), number of positions (4), pitch (0.100" / 2.54mm), number of rows (1), mounting type (free hanging in-line), contact termination (crimp), and moisture sensitivity level (MSL 1). Parts are classified into three substitution categories:

Direct Equivalent: Part 1375820-4 maintains identical electrical and mechanical parameters within the same manufacturer family (TE Connectivity CST-100 II series). This part is active and RoHS compliant, differing only in housing color (white versus natural) and series designation.

Parametric Equivalent: Part 0901560144 (Molex C-Grid III 90156 series) matches all critical parameters including pitch, position count, mounting type, contact termination, and fastening type. This part is active and ROHS3 compliant, with identical operating temperature range (-55°C to 105°C).

Similar Substitute: Parts 0010112043 (Molex KK254/7880 series) and 0022011042 (Molex KK250/5051 series) provide functional alternatives with parameter variations. Part 0010112043 maintains 0.100" (2.54mm) pitch and 4-position configuration but features non-gendered contact type. Part 0022011042 operates at 0.098" (2.50mm) pitch with polarizing key feature and different insulation material (PA66 versus PA).

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: 1375820-4

The TE Connectivity 1375820-4 is the recommended direct equivalent for 770602-4 replacement. This part maintains identical electrical and mechanical specifications within the same manufacturer ecosystem (TE Connectivity CST-100 II series). The part is active with confirmed RoHS compliance and unlimited moisture sensitivity rating. Housing color variation (white versus natural) does not affect functional compatibility. Current inventory of 2200 units supports production requirements.

Secondary Selection: 0901560144

The Molex 0901560144 (C-Grid III 90156 series) serves as a parametric equivalent when cross-manufacturer substitution is acceptable. This part matches all critical parameters including pitch, position count, mounting configuration, and contact termination. ROHS3 compliance and identical operating temperature range (-55°C to 105°C) ensure environmental performance parity. Insulation material differs (PPO versus PA), which may affect specific application requirements. Inventory of 7488 units is available.

Tertiary Selection: 0010112043

The Molex 0010112043 (KK254/7880 series) provides functional substitution with 0.100" (2.54mm) pitch and 4-position configuration. Contact type variation (non-gendered versus female socket) requires mechanical compatibility assessment with mating components. ROHS3 compliance and unlimited MSL rating are maintained. High inventory availability (100,856 units) supports volume requirements.

Not Recommended for Direct Substitution: 0022011042

The Molex 0022011042 (KK250/5051 series) operates at 0.098" (2.50mm) pitch, creating mechanical incompatibility with 0.100" (2.54mm) pitch specifications. Polarizing key feature and reduced operating temperature range (-25°C to 105°C) introduce additional parameter deviations. This part is suitable only for new designs requiring 2.50mm pitch specifications.

Frequently Asked Questions (FAQ)

Q: Can 1375820-4 directly replace 770602-4 in existing assemblies?

A: Yes. The 1375820-4 maintains identical pitch (0.100" / 2.54mm), position count (4), mounting type (free hanging in-line), contact termination (crimp), and fastening type (locking ramp). Housing color difference (white versus natural) does not affect electrical or mechanical function. Both parts feature MSL 1 rating and are compatible with identical contact sets.

Q: What is the primary difference between 0901560144 and 770602-4?

A: The 0901560144 is manufactured by Molex rather than TE Connectivity and belongs to the C-Grid III 90156 series. Insulation material differs (PPO versus unspecified PA in the original). All critical parameters including pitch, position count, mounting type, and fastening type are identical. Operating temperature range is identical (-55°C to 105°C).

Q: Why is 0022011042 listed as a substitute if the pitch differs?

A: The 0022011042 is classified as a similar substitute for applications requiring alternative pitch specifications. The 0.098" (2.50mm) pitch creates mechanical incompatibility with 0.100" (2.54mm) mating components. This part is suitable for new designs or applications where pitch flexibility exists, not for direct replacement of 770602-4.

Q: Are all substitute parts RoHS compliant?

A: The direct equivalent 1375820-4 is RoHS compliant. The parametric equivalent 0901560144 and similar substitutes 0010112043 and 0022011042 are ROHS3 compliant, which represents a more stringent standard. All parts meet or exceed RoHS requirements.

Q: What is the significance of MSL 1 rating across all parts?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture control requirements. All listed parts share this rating, eliminating moisture management as a differentiation factor during storage and handling.

Q: Does contact type variation between female socket and non-gendered affect compatibility?

A: Contact type affects mating component compatibility. Female socket contacts (770602-4, 1375820-4, 0901560144) are designed for male pin contacts. Non-gendered contacts (0010112043, 0022011042) accommodate either pin or socket mating. Mechanical compatibility with existing mating components must be assessed before substitution.

Q: What inventory considerations apply to part selection?

A: The 1375820-4 (direct equivalent) has 2200 units available. The 0901560144 (parametric equivalent) has 7488 units. The 0010112043 (similar substitute) has 100,856 units. Inventory levels support various production volumes, with 0010112043 offering maximum availability for high-volume applications.
