Key Parameters

Substitute Part Grouping Explanation

The PPPC102LFBN-RC from Sullins Connector Solutions qualifies as a substitute based on the following matching parameters:

• Number of Positions: 20
• Pitch - Mating: 0.100" (2.54mm)
• Number of Rows: 2
• Row Spacing - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Contact Finish - Mating: Gold
• Contact Shape: Square
• Contact Material: Phosphor Bronze
• Style: Board to Board
• Fastening Type: Push-Pull
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant

The substitute differs in connector type (header vs. elevated socket), contact configuration, and electrical ratings. These differences must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both components meet ROHS3 compliance and UL94 V-0 flammability requirements. The ESQ-110-44-G-D-LL maintains higher electrical performance specifications with 5.7A current rating and 550VAC voltage rating, along with an extended operating temperature range of -55°C to 125°C. The PPPC102LFBN-RC operates within -40°C to 105°C with reduced electrical ratings of 3A and 250V. Selection between these components depends on application electrical requirements and environmental operating conditions. Both components are actively produced and available in production quantities.

Frequently Asked Questions (FAQ)

Q: Can PPPC102LFBN-RC directly replace ESQ-110-44-G-D-LL in all applications?

A: No. While both connectors share the same 20-position, 0.100" pitch configuration and board-to-board mounting style, the PPPC102LFBN-RC has lower electrical ratings (3A vs. 5.7A per contact, 250V vs. 550VAC) and a narrower operating temperature range (-40°C to 105°C vs. -55°C to 125°C). Substitution is valid only when application requirements fall within the PPPC102LFBN-RC specifications.

Q: What are the key mechanical differences between these connectors?

A: The ESQ-110-44-G-D-LL is an elevated socket with forked contacts and kinked pin termination. The PPPC102LFBN-RC is a header connector with female socket contacts and standard solder termination. These differences affect mating interface compatibility and PCB layout considerations.

Q: Are both components RoHS compliant?

A: Yes. Both the ESQ-110-44-G-D-LL and PPPC102LFBN-RC are ROHS3 compliant and meet UL94 V-0 flammability requirements.

Q: What packaging formats are available?

A: The ESQ-110-44-G-D-LL is supplied in tube packaging, while the PPPC102LFBN-RC is supplied in tray packaging. Packaging selection may affect handling, storage, and assembly processes.

Q: Which connector supports higher current and voltage applications?

A: The ESQ-110-44-G-D-LL supports 5.7A per contact and 550VAC, making it suitable for higher-power applications. The PPPC102LFBN-RC is rated for 3A per contact and 250V, appropriate for lower-power signal and control applications.
