LED Holder H-177C Equivalent & Substitute Parts

Part Overview

The H-177C is an active LED holder manufactured by Bivar Inc., designed for T1 3/4 LED applications. This component is a right-angle standoff holder constructed from black nylon with a 0.350" (8.89mm) length specification. The H-177C is ROHS3 compliant and carries an MSL rating of 1 (Unlimited), indicating suitability for standard storage and handling conditions without moisture sensitivity constraints.

Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part specifications, enabling direct functional replacement in circuit designs and assembly applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the H-177C are identified based on the following critical parameters that determine functional compatibility:

Primary Matching Criteria:

• LED Type: T1 3/4 (exact match required)
• Color: Black (exact match required)
• Product Status: Active (ensures current availability)
• RoHS Compliance: ROHS3 Compliant (regulatory alignment)
• MSL Rating: 1 (Unlimited) (storage compatibility)

Secondary Consideration:

• Length tolerance: Parts within 0.015" (0.38mm) of the specified 0.350" dimension are classified as parametric equivalents due to mechanical fit requirements in standard LED mounting applications.
• Material variation: Nylon and PVC are both acceptable thermoplastic materials for LED holder construction, provided all other parameters remain constant.

The substitute parts ELM 1-350 and ELM 3-335 meet the primary matching criteria. ELM 1-350 maintains identical length specification (0.350"), while ELM 3-335 operates within acceptable length tolerance (0.335" vs. 0.350").

Parameter Comparison

Engineering Selection Recommendations

ELM 1-350 Selection Criteria: ELM 1-350 is a direct parametric equivalent to H-177C with identical length specification (0.350"). Both parts are manufactured by Bivar Inc., carry active product status, and maintain ROHS3 compliance with MSL 1 rating. The material difference (PVC vs. Nylon) does not affect functional performance in standard LED mounting applications. ELM 1-350 is suitable for direct substitution where inventory or supply chain considerations necessitate alternative sourcing.

ELM 3-335 Selection Criteria: ELM 3-335 operates within acceptable mechanical tolerance for LED holder applications, with a length of 0.335" (8.51mm) compared to the specified 0.350" (8.89mm). This 0.015" (0.38mm) dimensional variance falls within standard manufacturing tolerances for LED standoff holders. ELM 3-335 maintains all regulatory and compliance requirements identical to H-177C. Selection of ELM 3-335 is appropriate when the reduced standoff height is compatible with circuit board layout and LED positioning requirements.

Both substitute parts are active products with confirmed inventory availability and identical compliance certifications to the main part.

Frequently Asked Questions (FAQ)

Q: Can ELM 1-350 be used as a direct replacement for H-177C?

A: Yes. ELM 1-350 matches all critical parameters including LED type (T1 3/4), length (0.350"), color (Black), and compliance ratings (ROHS3, MSL 1). The material difference (PVC vs. Nylon) does not affect functional performance in standard applications.

Q: What is the significance of the 0.015" length difference between H-177C and ELM 3-335?

A: The 0.335" length of ELM 3-335 represents a 0.015" reduction from the H-177C specification of 0.350". This dimensional variance is within acceptable tolerance for LED standoff holder applications. Selection depends on circuit board layout requirements and LED positioning specifications in the target application.

Q: Are all three parts ROHS3 compliant?

A: Yes. H-177C, ELM 1-350, and ELM 3-335 are all ROHS3 compliant with MSL 1 (Unlimited) ratings, ensuring regulatory alignment and standard storage compatibility.

Q: Does material composition (Nylon vs. PVC) affect substitution compatibility?

A: Both Nylon and PVC are acceptable thermoplastic materials for LED holder construction. Material selection does not impact electrical performance or mechanical fit in standard T1 3/4 LED applications. Substitution is valid based on material compatibility with the target application environment.

Q: What packaging format is used for all three parts?

A: All three parts (H-177C, ELM 1-350, and ELM 3-335) are supplied in Bag packaging format, ensuring consistent handling and inventory management across substitute selections.
