Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 145154-1 is determined by strict equivalence across all electrical and mechanical parameters. The substitute part 5145154-1 maintains identical specifications for connector function, including 120-position configuration, 0.050" pitch, female gender, PCI card edge type, dual read-out capability, and through-hole solder termination with staggered contact arrangement.

The primary distinction between the main part and its substitute is packaging format and RoHS compliance status. The 145154-1 is supplied in standard packaging with RoHS non-compliant status, while the 5145154-1 is supplied in bulk packaging and meets ROHS3 compliance requirements. Both parts share the same base product number family (145154 series) and are manufactured by TE Connectivity AMP Connectors.

Substitution is valid when the following parameters are matched:

• Number of positions: 120
• Pitch: 0.050" (1.27mm)
• Card type: PCI™
• Gender: Female
• Mounting type: Through hole
• Contact material: Phosphor bronze
• Contact finish: Gold
• Termination: Solder, staggered
• Read out: Dual
• Board guide feature: Present

Parameter Comparison

Engineering Selection Recommendations

Both the 145154-1 and 5145154-1 are active production parts manufactured by TE Connectivity AMP Connectors and are electrically and mechanically equivalent for PCI card edge connector applications. Selection between these parts is determined by compliance and packaging requirements.

The 145154-1 is suitable for applications where RoHS non-compliant components are acceptable and standard packaging is preferred. The 5145154-1 is the appropriate selection for applications requiring ROHS3 compliance or bulk packaging formats. Both parts maintain identical electrical performance, contact characteristics, and mechanical fit within PCI card edge slot configurations.

The substitute part 5145154-1 offers higher current inventory availability at 1470 pieces compared to 1131 pieces for the main part, which may influence procurement lead times and supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Are the 145154-1 and 5145154-1 electrically identical?

A: Yes. Both parts are 120-position female PCI card edge connectors with identical electrical specifications, including phosphor bronze contacts with gold flash finish, 0.050" pitch, dual read-out configuration, and solder termination with staggered contact arrangement.

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

A: The primary differences are packaging format and RoHS compliance status. The 145154-1 uses standard packaging and is RoHS non-compliant, while the 5145154-1 uses bulk packaging and meets ROHS3 compliance requirements.

Q: Can the 5145154-1 be used as a direct replacement for the 145154-1?

A: Yes, the 5145154-1 is a direct substitute for the 145154-1 in all PCI card edge connector applications where the mechanical and electrical parameters match. Bulk packaging does not affect connector performance or compatibility.

Q: Does RoHS compliance affect connector performance?

A: No. RoHS compliance status reflects manufacturing process and material sourcing standards but does not alter the electrical or mechanical performance of the connector. Both parts deliver identical functional characteristics.

Q: What is the significance of the "Standard Edge .050" series designation?

A: This designation indicates the connector series classification based on card edge type and contact pitch. Both parts belong to this series, confirming their mechanical and electrical compatibility within PCI card edge applications.

Q: Are there any operating temperature limitations for these connectors?

A: Operating temperature specifications are not provided in the part data. Consult the manufacturer's technical documentation for thermal operating range and derating information specific to your application environment.

Q: What does "Dual Read Out" mean in the context of these connectors?

A: Dual read-out indicates the connector supports signal detection or contact verification from both sides of the card edge interface, enabling redundant or confirmatory signal path monitoring.

Q: Is the board guide feature critical for connector installation?

A: The board guide feature provides mechanical alignment and stabilization during card insertion into the connector. This feature is present on both the 145154-1 and 5145154-1 and is integral to proper connector function.
