ELFH02150 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The ELFH02150 is a 2-position vertical terminal block header manufactured by Amphenol PCD. This shrouded male pin connector operates at 300V UL and 15A UL current rating with a 5.00mm pitch, designed for through-hole solder termination. The component is actively produced and RoHS compliant, serving as a standard interconnection solution in industrial and commercial applications. Substitute parts may be required due to inventory availability, regional sourcing preferences, or specific mechanical packaging constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELFH02150 is determined by the following critical parameters:

Primary Compatibility Criteria:

• 2-position configuration with 0.197" (5.00mm) pitch spacing
• Vertical through-hole solder termination
• Male pin header type with shrouded design
• 300V UL voltage rating minimum
• UL94 V-0 flammability rating
• Tin contact mating finish

Acceptable Variations:

• Shroud configuration (4-side vs. 2-side) does not prevent substitution
• Current rating of 12A UL or higher satisfies the 15A UL requirement when voltage and pitch specifications are maintained
• Housing material composition (PBT, Polyamide, or Thermoplastic Resin) is acceptable provided flammability rating is maintained
• Operating temperature range variations are acceptable if minimum -40°C and maximum 105°C are supported
• Contact material (Brass or Copper Alloy) is acceptable with tin finish

Pitch Tolerance:

• 0.197" (5.00mm) and 0.200" (5.08mm) pitches are considered equivalent for substitution purposes within this product category

The following parts meet these criteria and are listed as approved substitutes.

Parameter Comparison

Engineering Selection Recommendations

1753437 (Phoenix Contact COMBICON MSTBV Series)

This substitute maintains identical pitch (5.00mm) and voltage rating (300V UL). The primary difference is the 2-side shroud configuration versus the 4-side shroud of the main part. Current rating is 12A UL, which is lower than the main part's 15A UL specification. This part is actively produced and ROHS3 compliant. Selection is appropriate when 12A current capacity is sufficient for the application and 2-side shroud geometry is acceptable.

OQ0253500000G (Amphenol Anytek 06-508 Series)

This substitute operates at a 0.200" (5.08mm) pitch, representing a 0.08mm deviation from the main part's 5.00mm pitch. Voltage rating matches at 300V UL. Current rating is 12A UL. Operating temperature range extends to 115°C, exceeding the main part's 105°C maximum. The part is actively produced and ROHS3 compliant. Selection is appropriate when the slight pitch tolerance is acceptable within PCB layout constraints and 12A current capacity meets application requirements.

Both substitutes maintain UL94 V-0 flammability compliance and tin contact finish. Selection between substitutes should be based on specific PCB pitch requirements and current capacity needs.

Frequently Asked Questions (FAQ)

Q: Can the 1753437 substitute for ELFH02150 in all applications?

A: The 1753437 is compatible when the application current requirement does not exceed 12A UL. The identical 5.00mm pitch and 300V UL voltage rating ensure mechanical and electrical compatibility. The 2-side shroud configuration differs from the 4-side shroud of the main part but does not prevent substitution.

Q: What is the pitch difference between ELFH02150 and OQ0253500000G?

A: The ELFH02150 operates at 0.197" (5.00mm) pitch, while the OQ0253500000G operates at 0.200" (5.08mm) pitch. This represents a 0.08mm difference. Substitution is acceptable when PCB layout tolerances accommodate this spacing variation.

Q: Are all substitute parts RoHS compliant?

A: The main part ELFH02150 is RoHS Compliant. Both substitute parts (1753437 and OQ0253500000G) are ROHS3 Compliant, which represents a more recent compliance standard. All three parts meet RoHS requirements.

Q: What is the current rating difference between the main part and substitutes?

A: The ELFH02150 is rated for 15A UL. Both substitute parts (1753437 and OQ0253500000G) are rated for 12A UL. Substitution is appropriate when the application current requirement does not exceed 12A UL.

Q: Do the substitute parts have different operating temperature ranges?

A: The ELFH02150 operates from -40°C to 105°C. The 1753437 does not specify an operating temperature range. The OQ0253500000G operates from -40°C to 115°C, providing a higher maximum temperature capability.

Q: What is the difference in shroud configuration?

A: The ELFH02150 features a 4-side shroud design. Both substitute parts (1753437 and OQ0253500000G) feature 2-side shroud designs. Both configurations provide male pin protection and are suitable for vertical through-hole applications.

Q: Can I use OQ0253500000G if my PCB is designed for 5.00mm pitch?

A: The OQ0253500000G operates at 5.08mm pitch. Substitution requires verification that PCB layout tolerances can accommodate the 0.08mm pitch difference. If the PCB is rigidly designed for 5.00mm spacing, the OQ0253500000G may not be compatible.
