ELFH19160 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The ELFH19160 is a 19-position terminal block header manufactured by Amphenol PCD, designed for vertical through-hole mounting with 5.00mm pitch spacing. This component is classified as an active product and serves as an interface for wire-to-board connections in industrial and commercial applications. The part features male pins with 2-side shrouding, solder termination, and operates within a temperature range of -40°C to 105°C. Equivalent and substitute parts are identified to provide procurement flexibility, inventory alternatives, and continuity of supply for applications requiring compatible 19-position vertical terminal block headers with matching electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELFH19160 is determined by strict alignment of the following critical parameters:

Core Compatibility Criteria:

• Number of Positions: 19 (exact match required)
• Pitch: 0.197" (5.00mm) (exact match required)
• Header Orientation: Vertical (exact match required)
• Termination Style: Solder (exact match required)
• Mounting Type: Through Hole (exact match required)
• Pin Configuration: Male Pins (exact match required)

Acceptable Variation Parameters:

• Shrouding Configuration: 2-side or 4-side shrouding are functionally compatible for wire retention and mechanical stability
• Housing Material: PBT and Polyamide (PA/Nylon) are both acceptable thermoplastic materials meeting UL94 V-0 flammability requirements
• Contact Tail Length: Variations within 0.001" (0.04mm) are acceptable for PCB mounting compatibility
• Insulation Height: Variations within 0.003" (0.07mm) are acceptable for board clearance

The substitute part 1755671 (Phoenix Contact COMBICON MSTBVA series) meets all core compatibility criteria and operates within acceptable mechanical tolerances.

Parameter Comparison

Engineering Selection Recommendations

ELFH19160 (Amphenol PCD) is recommended for applications requiring:

• UL current rating of 15 A
• PBT housing material
• 2-side shrouding configuration
• Active product status with established supply chain

1755671 (Phoenix Contact) is recommended for applications requiring:

• 4-side shrouding for enhanced wire retention and environmental protection
• IEC compliance documentation (12 A at 400 V IEC rating)
• Polyamide housing material
• REACH compliance certification
• Higher inventory availability (1150 pcs vs. 733 pcs)

Both parts maintain UL94 V-0 flammability compliance, tin contact mating finish, and unlimited moisture sensitivity level (MSL 1). Selection between these parts should be based on specific application requirements regarding shrouding configuration, housing material preference, and current rating demands. The 3 A difference in UL current rating (15 A vs. 12 A) must be evaluated against actual circuit requirements.

Frequently Asked Questions (FAQ)

Q: Can 1755671 directly replace ELFH19160 in existing designs?

A: Yes, for applications operating at or below 12 A UL current rating. The 4-side shrouding of 1755671 provides additional wire retention compared to the 2-side shrouding of ELFH19160. PCB footprint compatibility is maintained due to matching pitch (5.00mm), position count (19), and contact tail length variance of only 0.001".

Q: What is the significance of the shrouding difference (2-side vs. 4-side)?

A: 2-side shrouding (ELFH19160) provides lateral wire retention. 4-side shrouding (1755671) provides enhanced retention on all sides, offering improved mechanical stability and environmental protection. Both configurations are functionally compatible for standard through-hole PCB mounting.

Q: Are there current rating limitations when substituting?

A: Yes. The ELFH19160 is rated for 15 A (UL), while 1755671 is rated for 12 A (UL). If the application requires current above 12 A, 1755671 cannot be used as a substitute. Applications operating at 12 A or below can safely use either part.

Q: Do housing material differences affect performance?

A: Both PBT (ELFH19160) and Polyamide/Nylon (1755671) meet UL94 V-0 flammability requirements and are suitable for industrial applications. Material selection depends on specific environmental conditions, chemical exposure, and mechanical stress requirements of the application.

Q: What packaging differences exist between these parts?

A: ELFH19160 is supplied in Tray packaging (733 pcs available), while 1755671 is supplied in Bulk packaging (1150 pcs available). Packaging format may affect handling, storage, and integration into assembly processes.

Q: Are both parts RoHS compliant?

A: Yes. ELFH19160 is RoHS Compliant, and 1755671 is ROHS3 Compliant. Both meet current RoHS requirements. Additionally, 1755671 carries REACH Unaffected certification.
