Substitute Part Grouping Explanation

Substitution between the TE Connectivity 145274-1 and 5145274-1 is based on electrical and mechanical parameter equivalence. Both connectors maintain identical specifications across all critical functional parameters: 26-position configuration, dual-edge card type, 0.100" pitch, 2-row layout, card thickness tolerance, female gender, phosphor bronze contact material with gold finish, through-hole mounting, press-fit termination, and -55°C to 85°C operating temperature range.

The primary distinction between these parts is packaging format and regulatory compliance status. The 145274-1 is supplied in standard packaging, while the 5145274-1 is supplied in bulk packaging. Additionally, the 5145274-1 carries RoHS Compliant certification, whereas the 145274-1 is RoHS non-compliant. These differences do not affect the connector's functional performance or electrical characteristics in equivalent applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 145274-1 and 5145274-1 are functionally equivalent 26-position female card edge connectors suitable for identical applications. Selection between these parts should be based on specific project requirements:

145274-1 is appropriate for applications where standard packaging is required and RoHS compliance is not a mandatory specification. This part maintains active production status with adequate inventory availability.

5145274-1 is appropriate for applications requiring RoHS Compliant certification or bulk packaging formats. This part offers higher inventory availability and meets regulatory requirements for restricted substance compliance. Both parts share identical electrical and mechanical characteristics, ensuring direct functional interchangeability in circuit designs and PCB layouts.

Frequently Asked Questions (FAQ)

Q: Are the 145274-1 and 5145274-1 electrically identical?

A: Yes. Both connectors feature identical electrical specifications including 26-position configuration, 0.100" pitch, phosphor bronze contacts with gold finish, and -55°C to 85°C operating temperature range. Electrical performance and signal integrity characteristics are equivalent.

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

A: The primary differences are packaging format and RoHS compliance status. The 145274-1 uses standard packaging and is RoHS non-compliant, while the 5145274-1 uses bulk packaging and is RoHS Compliant. All functional and mechanical specifications remain identical.

Q: Can I substitute 5145274-1 for 145274-1 in existing designs?

A: Yes. The 5145274-1 is a direct substitute for the 145274-1. Both connectors accommodate the same card thickness range (0.054" to 0.070"), feature identical press-fit termination, and maintain the same through-hole mounting configuration. No design modifications are required.

Q: Does packaging format affect connector performance?

A: No. Packaging format (standard versus bulk) does not affect electrical performance, mechanical fit, or operational characteristics. The choice between packaging formats is determined by procurement, inventory management, and supply chain requirements.

Q: Which part should I select for RoHS-compliant applications?

A: The 5145274-1 is RoHS Compliant and is the appropriate selection for applications requiring restricted substance compliance. The 145274-1 is RoHS non-compliant and should not be used in applications with RoHS requirements.

Q: Are both parts currently in production?

A: Yes. Both the 145274-1 and 5145274-1 maintain Active product status. The 5145274-1 has higher inventory availability (1822 units) compared to the 145274-1 (718 units).

Q: What card thickness do these connectors support?

A: Both connectors support card thickness between 0.054" and 0.070" (1.37mm to 1.78mm). This tolerance range accommodates standard dual-edge card designs within the specified thickness parameters.
