Key Parameters

Substitute Part Grouping Explanation

Substitution of the 307-012-532-101 is determined by the following critical parameters:

• Number of Positions: Must be 12
• Gender: Must be Female
• Pitch: Must be 0.156" (3.96mm)
• Card Type: Single Edge configuration
• Contact Finish: Gold plating
• Operating Temperature Range: -40°C to 105°C minimum
• Insulation Material: Polyester Thermoplastic
• RoHS Compliance: ROHS3 Compliant

The substitute part 307-012-525-101 meets all critical substitution criteria. While this substitute introduces additional specifications (card thickness tolerance range, semi-bellows contact type, and solder termination), these represent enhanced or more precisely defined characteristics that maintain functional compatibility with the original connector specification.

Parameter Comparison

Engineering Selection Recommendations

The 307-012-525-101 is the direct substitute for the obsolete 307-012-532-101. Both parts maintain identical electrical and mechanical compatibility across all critical interface parameters. The substitute part carries active product status, ensuring continued availability and supply chain reliability.

Both components satisfy ROHS3 compliance and unlimited moisture sensitivity requirements, making them suitable for equivalent applications. The substitute part specifies card thickness tolerance as 0.054" to 0.070" (1.37mm to 1.78mm), which encompasses the original part's 0.062" (1.57mm) specification. The substitute also defines contact type as semi-bellows with solder termination, providing enhanced mechanical and electrical performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can the 307-012-525-101 directly replace the 307-012-532-101 in existing designs?

A: Yes. Both connectors share identical pitch (0.156"), position count (12), gender (female), card type (single edge), contact finish (gold), operating temperature range (-40°C to 105°C), and insulation material (polyester thermoplastic). The substitute part's card thickness tolerance range (0.054" to 0.070") encompasses the original specification of 0.062".

Q: What is the primary reason for substitution?

A: The 307-012-532-101 is classified as obsolete. The 307-012-525-101 is an active product from the same manufacturer and series, providing equivalent functionality with assured supply availability.

Q: Are there compliance differences between these parts?

A: No. Both parts are ROHS3 compliant and carry unlimited moisture sensitivity level (MSL 1), meeting identical regulatory and environmental requirements.

Q: Does the substitute part's solder termination affect compatibility?

A: The termination method is a manufacturing characteristic that does not affect the connector's electrical or mechanical interface with the card edge. Both parts maintain the same contact interface specifications.

Q: What is the significance of the card thickness tolerance range in the substitute part?

A: The substitute part specifies a tolerance range (0.054" to 0.070") rather than a fixed dimension. The original part's 0.062" thickness falls within this range, confirming mechanical compatibility.
