Substitute Part Grouping Explanation

The four substitute parts (1934303-1, 1934304-1, 1934305-1, 1934306-1) are TE Connectivity AMP Connectors from the Z-PACK TinMan series. These parts share the following critical parameters with the Molex 0761551833:

96-position connector header configuration
Male pin connector type
Through-hole mounting
Press-fit termination
12 rows × 8 columns layout
Gold contact finish at 30.0µin (0.76µm) thickness
Black color
UL94 V-0 flammability rating
ROHS3 compliance
MSL 1 rating

Substitution is based on these matching electrical and mechanical parameters. The TE Connectivity parts differ in pitch specification (0.075" / 1.90mm versus 0.053" / 1.35mm), operating temperature range (-65°C ~ 90°C versus -55°C ~ 85°C), voltage rating (250V versus 30V), and current rating (0.5A specified versus unspecified for the Molex part). These differences must be evaluated against specific application requirements.

Engineering Selection Recommendations

All parts listed maintain Active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment. The Molex 0761551833 and all four TE Connectivity substitutes carry UL94 V-0 flammability certification and MSL 1 moisture sensitivity rating, indicating equivalent environmental performance characteristics.

The primary distinction between the Molex part and TE Connectivity alternatives is pitch specification. The Molex 0761551833 operates at 0.053" (1.35mm) pitch, while all TE Connectivity substitutes operate at 0.075" (1.90mm) pitch. This pitch difference directly affects PCB footprint dimensions and contact spacing. Substitution is only valid when the application PCB layout accommodates the 0.075" pitch specification.

The TE Connectivity parts provide higher voltage (250V versus 30V) and specified current (0.5A) ratings, along with an extended operating temperature range (-65°C ~ 90°C versus -55°C ~ 85°C). These enhanced specifications support broader application requirements without performance degradation.

Frequently Asked Questions (FAQ)

Q: Can TE Connectivity parts 1934303-1, 1934304-1, 1934305-1, and 1934306-1 directly replace Molex 0761551833?

A: Direct replacement depends on PCB footprint compatibility. The critical difference is pitch: Molex 0761551833 uses 0.053" (1.35mm) pitch, while all TE Connectivity substitutes use 0.075" (1.90mm) pitch. If the PCB is designed for 0.053" pitch, these parts cannot be used without PCB redesign. If the application permits 0.075" pitch, substitution is valid based on matching connector type, position count, mounting method, and termination style.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by: 96-position configuration, male pin header type, through-hole mounting, press-fit termination, 12×8 row/column layout, gold contact finish, black color, UL94 V-0 flammability rating, ROHS3 compliance, and MSL 1 rating. Pitch specification is the primary limiting factor for physical compatibility.

Q: Do the TE Connectivity parts offer performance advantages?

A: TE Connectivity parts specify 0.5A current rating and 250V voltage rating compared to the Molex part's 30V rating. They also provide an extended operating temperature range of -65°C ~ 90°C versus -55°C ~ 85°C. These specifications indicate capability for higher-power applications, though the Molex part remains suitable for its specified 30V operating envelope.

Q: Are all four TE Connectivity substitute parts electrically equivalent?

A: Yes. Parts 1934303-1, 1934304-1, 1934305-1, and 1934306-1 share identical electrical and mechanical specifications. They differ only in base product number designation and inventory availability. Selection among these four parts can be based on supply chain considerations or packaging preference (all supplied in Tube packaging).

Q: What compliance certifications apply to all listed parts?

A: All parts are ROHS3 compliant, carry UL94 V-0 flammability certification, and maintain MSL 1 (Unlimited) moisture sensitivity rating. All parts are designated Active status, ensuring continued manufacturer support and availability.
