Substitute Part Grouping Explanation

Substitution of the obsolete 63648-2 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part 63648-1 maintains identical specifications for tab width (0.250"), tab thickness (0.032"), tab length (0.305"), wire gauge range (14-20 AWG), termination method (crimp), insulation type (non-insulated), mounting configuration (free hanging in-line), contact material (brass), and insulation diameter range (0.085" ~ 0.135"). Both parts share the same base product number (63648) and series designation (Faston), confirming functional equivalence. The primary distinction is product status: 63648-2 is obsolete while 63648-1 is active, and packaging differs (63648-1 is supplied in cut tape format). Compliance certifications including ROHS3 and MSL rating remain consistent across both parts.

The 63648-1 is supplied in cut tape packaging, which is standard for high-volume production environments and component handling systems. All electrical and mechanical parameters remain constant between the two parts, confirming direct interchangeability in circuit applications. The transition from 63648-2 to 63648-1 presents no technical barriers to implementation.

Frequently Asked Questions (FAQ)

Q: Can 63648-1 be used as a direct replacement for 63648-2 in existing designs?

A: Yes. The 63648-1 maintains identical electrical and mechanical specifications across all critical parameters including tab dimensions, wire gauge range, termination method, contact material, and insulation characteristics. Direct substitution is supported without design modification.

Q: What is the primary reason for substituting 63648-2?

A: The 63648-2 is classified as obsolete. The 63648-1 is an active product with equivalent specifications, ensuring continued component availability and supply chain continuity.

Q: Are there compliance differences between 63648-2 and 63648-1?

A: No. Both parts maintain identical ROHS3 compliance status and MSL rating of 1 (unlimited). Regulatory and environmental certifications are equivalent.

Q: How does packaging differ between these parts?

A: The 63648-2 packaging specification is not provided in available documentation. The 63648-1 is supplied in cut tape (CT) format, which is standard for automated assembly and component handling systems.

Q: Are the contact finish specifications identical?

A: The 63648-2 specifies tin contact finish. The 63648-1 contact finish specification is not provided in available documentation. Both parts use brass as the base contact material.

Q: What wire gauge range is supported by both parts?

A: Both 63648-2 and 63648-1 support 14-20 AWG wire gauges with insulation diameter range of 0.085" to 0.135" (2.16mm to 3.43mm).

Q: Is the Faston series designation consistent across both parts?

A: Yes. Both 63648-2 and 63648-1 belong to the Faston series and share the same base product number (63648), confirming series equivalence.
