• Row Configuration: 2 rows with 0.079" (2.00mm) row spacing
• Mounting & Termination: Through-hole solder termination
• Electrical Performance: 2A current rating, 200V voltage rating
• Contact Finish: Gold-plated mating contacts
• Operating Range: -55°C to 125°C
• Series Compatibility: Minitek® 2.00mm series

The substitute part 63453-050LF maintains identical electrical and mechanical specifications while offering active product status and improved compliance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 63453-050LF is the direct substitute for the obsolete 63453-050. Both parts share identical electrical and mechanical specifications across all critical parameters including connector geometry, contact configuration, pitch, current and voltage ratings, and operating temperature range.

The primary distinction between these parts is product status and regulatory compliance. The 63453-050LF maintains active product status with Amphenol ICC, ensuring continued availability and manufacturing support. Additionally, the 63453-050LF is RoHS compliant, whereas the original 63453-050 is non-compliant. For applications subject to RoHS requirements or requiring long-term component availability, the 63453-050LF is the appropriate selection.

Both parts carry identical MSL rating (1 - Unlimited), ECCN classification (EAR99), and HTSUS code (8536.69.4040). The packaging difference (bulk versus tube) does not affect functional or electrical performance.

Frequently Asked Questions (FAQ)

Q: Are the 63453-050 and 63453-050LF mechanically interchangeable?

A: Yes. Both parts are identical in all mechanical dimensions, including connector body profile, contact spacing, mounting hole positions, and insulation height. They are direct mechanical substitutes.

Q: Are the 63453-050 and 63453-050LF electrically interchangeable?

A: Yes. Both parts have identical electrical specifications: 2A current rating, 200V voltage rating, gold-plated mating contacts with 8.00µin finish thickness, and operating temperature range of -55°C to 125°C.

Q: What is the difference between the 63453-050 and 63453-050LF?

A: The primary differences are product status and RoHS compliance. The 63453-050 is obsolete and RoHS non-compliant. The 63453-050LF is an active product with RoHS compliance. Packaging also differs: the original uses bulk packaging while the substitute uses tube packaging.

Q: Can I use the 63453-050LF in place of the 63453-050 in existing designs?

A: Yes. The 63453-050LF is a direct substitute with no design modifications required. All electrical and mechanical parameters are identical.

Q: Does the tube packaging of the 63453-050LF affect compatibility?

A: No. Packaging format does not affect the connector's electrical or mechanical performance. Tube packaging is a handling and storage consideration only.

Q: Are both parts suitable for industrial and medical applications?

A: Yes. Both the 63453-050 and 63453-050LF are rated for general purpose, industrial, and medical applications with UL94 V-0 flammability rating and MSL 1 (Unlimited) moisture sensitivity.
