Substitute Part Grouping Explanation

The 307-086-540-201 qualifies as a direct substitute for the 307-086-544-201 based on the following critical parameters that determine functional compatibility:

Matching Parameters:

• Number of Positions: 86
• Gender: Female
• Pitch: 0.156" (3.96mm)
• Card Type: Non Specified - Dual Edge
• Number of Rows: 2
• Mounting Type: Through Hole
• Termination: Wire Wrap
• Contact Finish: Gold
• Operating Temperature Range: -40°C ~ 105°C
• Material - Insulation: Polyester Thermoplastic
• RoHS Status: ROHS3 Compliant
• Series: 307

Allowable Variation:

• Card Thickness: The substitute part accepts 0.054" ~ 0.070" (1.37mm ~ 1.78mm), which encompasses the main part's 0.062" (1.57mm) specification within its tolerance range.

The substitute part is currently in active production status, ensuring ongoing availability and supply chain support.

Parameter Comparison

Engineering Selection Recommendations

The 307-086-540-201 is the appropriate substitute for the obsolete 307-086-544-201. Both parts maintain identical electrical and mechanical specifications across all critical functional parameters. The substitute part is manufactured by the same supplier and carries active product status, ensuring long-term availability.

Both parts satisfy ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The substitute part's card thickness tolerance of 0.054" ~ 0.070" (1.37mm ~ 1.78mm) accommodates the main part's 0.062" (1.57mm) specification, confirming mechanical compatibility in existing applications.

The transition from the obsolete 307-086-544-201 to the active 307-086-540-201 presents no technical barriers and is supported by identical series designation (307), connector architecture, and termination methodology.

Frequently Asked Questions (FAQ)

Q: Can the 307-086-540-201 directly replace the 307-086-544-201 in existing applications?

A: Yes. Both connectors share identical position count (86), pitch (0.156"), gender (female), row configuration (2), and termination method (wire wrap). The substitute part's card thickness tolerance encompasses the main part's specification.

Q: What is the significance of the card thickness tolerance difference?

A: The main part specifies a fixed card thickness of 0.062" (1.57mm). The substitute part accepts cards within the range 0.054" ~ 0.070" (1.37mm ~ 1.78mm). This tolerance range includes the main part's specification, confirming mechanical compatibility.

Q: Are there compliance differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

Q: Why is the substitute part listed as active while the main part is obsolete?

A: The 307-086-540-201 represents the current production equivalent within the 307 series. The obsolete status of the 307-086-544-201 reflects its discontinuation from active manufacturing, making the substitute part the recommended selection for new designs and ongoing system support.

Q: Are there differences in contact material specifications?

A: The main part specifies Copper, Nickel, Tin Alloy contacts. The substitute part specifies Copper Alloy contacts. Both maintain gold finish with equivalent electrical performance characteristics for wire wrap termination applications.

Q: What is the packaging difference between these parts?

A: The main part packaging is not specified. The substitute part is supplied in bulk packaging, which is standard for card edge connector distribution.
