Molex 0761552608 Equivalent & Substitute Parts

Part Overview

The Molex 0761552608 is a 192-position backplane connector header with male pins designed for through-hole PCB mounting. This connector features an Impact style with guide left configuration, operating across a temperature range of -55°C to 85°C with a 30V voltage rating. The part is classified as obsolete, making identification of equivalent and substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitute relationships for the Molex 0761552608 are determined by the following critical parameters: connector type (header, male pins), number of positions (192), mounting method (through hole), termination style (press-fit), contact finish (gold), material flammability rating (UL94 V-0), and compliance certifications (ROHS3).

The substitute parts are grouped into two categories:

Direct Equivalent (Same Series): Molex 0761553608 maintains identical electrical and mechanical specifications within the Impact 76155 series, differing only in product status (active vs. obsolete) and packaging format (tray vs. standard).

Cross-Manufacturer Substitute (Different Series): TE Connectivity 1934316-1 provides functional substitution as a 192-position header with male pins and through-hole mounting. However, this part operates under different mechanical parameters, including a larger pitch (0.075" vs. 0.053"), higher voltage rating (250V vs. 30V), and specified current rating (0.5A), making it suitable for applications where these enhanced specifications are compatible with the original design requirements.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: Molex 0761553608 is the primary substitute for the obsolete 0761552608. Both parts maintain identical electrical and mechanical specifications within the Impact 76155 series. The 0761553608 is currently in active production status with 822 units in stock, providing supply continuity for existing designs. This part is ROHS3 compliant and carries the same UL94 V-0 flammability rating.

For Cross-Manufacturer Substitution: TE Connectivity 1934316-1 serves as an alternative when Molex parts are unavailable. This part differs in pitch specification (0.075" vs. 0.053"), which affects PCB layout compatibility. The TE part provides enhanced electrical specifications with a 250V voltage rating and 0.5A current rating, suitable for applications requiring higher electrical performance margins. The operating temperature range extends to -65°C, providing broader environmental coverage. RoHS compliance is confirmed, though REACH status is listed as vendor undefined.

Selection between these substitutes depends on PCB layout constraints (pitch compatibility) and electrical requirement margins. Direct replacement with Molex 0761553608 is recommended when layout permits. Cross-manufacturer substitution with TE 1934316-1 requires PCB redesign due to pitch differences but offers enhanced electrical specifications.

Frequently Asked Questions (FAQ)

Q: Can Molex 0761553608 be used as a direct replacement for 0761552608?

A: Yes. Both parts share identical connector type, position count (192), pitch (0.053"), mounting method (through hole), termination style (press-fit), contact finish (gold), and flammability rating (UL94 V-0). The primary difference is product status: 0761552608 is obsolete while 0761553608 is active production. Packaging differs (tray vs. standard), but electrical and mechanical compatibility is complete.

Q: What are the limitations of using TE Connectivity 1934316-1 as a substitute?

A: The TE part operates at a different pitch (0.075" vs. 0.053"), requiring PCB redesign for hole spacing and trace routing. The larger pitch increases overall connector footprint. Additionally, the connector style differs (high speed vs. impact guide left). While electrical specifications are enhanced (250V vs. 30V, 0.5A current rating), mechanical compatibility with existing PCB designs is not maintained.

Q: Are all substitute parts RoHS compliant?

A: Yes. Molex 0761552608 and 0761553608 are ROHS3 compliant. TE Connectivity 1934316-1 is RoHS compliant. All three parts meet RoHS requirements for hazardous substance restrictions.

Q: What is the impact of pitch differences on PCB compatibility?

A: Pitch determines the spacing between connector pins and corresponding PCB holes. The Molex parts use 0.053" (1.35mm) pitch, while the TE part uses 0.075" (1.90mm) pitch. Existing PCBs designed for Molex connectors cannot accommodate the TE connector without complete redesign of the connector footprint and associated traces.

Q: Are there inventory considerations for these substitutes?

A: Molex 0761552608 (obsolete) has 857 units in stock. Molex 0761553608 (active) has 822 units in stock. TE Connectivity 1934316-1 (active) has 1082 units in stock. For long-term supply assurance, the active production parts (0761553608 or 1934316-1) are preferred over the obsolete 0761552608.
