HLEM10R-1RLF Equivalent & Substitute Parts

Part Overview

The HLEM10R-1RLF is a 10-position FFC/FPC connector manufactured by Amphenol ICC (FCI) with top-mounted contacts, right-angle through-hole mounting, and 1.25mm pitch. This connector is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement continuity. The part features kinked pin termination, tin contact finish, and operates across -55°C to 85°C with a 200V voltage rating and 1A current capacity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HLEM10R-1RLF is determined by the following critical parameters:

• Position Count: 10 positions (exact match required)
• Pitch: 0.049" (1.25mm) (exact match required)
• Mounting Configuration: Through hole, right-angle orientation (exact match required)
• Contact Arrangement: Top-mounted contacts (exact match required)
• Voltage Rating: Minimum 200V (equal or higher acceptable)
• Current Rating: Minimum 1A (equal or higher acceptable)
• Connector Type: FFC/FPC flat flexible connector (exact match required)
• Flammability Rating: UL94 V-0 (equal or higher acceptable)

The substitute part 0039532104 (Molex 5597 series) meets all critical substitution criteria. Differences in termination method (solder vs. kinked pin), contact finish composition (tin bismuth vs. tin), and height above board are acceptable variations within the FFC/FPC connector category, provided the core electrical and mechanical parameters align.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0039532104 connector is a suitable substitute for the obsolete HLEM10R-1RLF based on the following factors:

Product Status: The HLEM10R-1RLF is obsolete, while the 0039532104 is actively manufactured and maintained by Molex, ensuring long-term availability and supply chain stability.

Electrical Compliance: Both connectors meet identical voltage (200V) and current (1A) ratings with UL94 V-0 flammability certification, satisfying regulatory and safety requirements.

Mechanical Compatibility: Core mechanical parameters—10 positions, 1.25mm pitch, through-hole right-angle mounting, and top-contact configuration—are identical, enabling direct footprint compatibility on PCB designs.

Environmental Certification: Both parts carry REACH Unaffected and EAR99 ECCN classifications, maintaining compliance with export and environmental regulations.

Operational Considerations: The substitute operates within a narrower temperature range (-20°C to 80°C versus -55°C to 85°C). Applications requiring the full -55°C to 85°C range must evaluate this limitation. The substitute is 0.016" taller above the board (5.40mm vs. 5.00mm), which may require clearance verification in space-constrained designs. Termination differs (solder vs. kinked pin), requiring assembly process adjustment.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0039532104 be used as a direct replacement for the HLEM10R-1RLF?

A: Yes, for applications operating within -20°C to 80°C. The electrical ratings, position count, pitch, and mounting configuration are identical. PCB footprints are compatible. Assembly process changes are required due to solder termination versus kinked pin termination.

Q: What are the key differences between these connectors?

A: Operating temperature range is narrower on the substitute (-20°C to 80°C vs. -55°C to 85°C). Height above board differs by 0.016" (5.40mm vs. 5.00mm). Termination method differs (solder vs. kinked pin). Contact finish composition differs (tin bismuth vs. tin). All other critical parameters match.

Q: Does the height difference affect PCB design?

A: The 0.016" (0.4mm) height increase must be evaluated for clearance in applications with space constraints above the connector. Standard PCB designs typically accommodate this variation without modification.

Q: Are there compliance or certification concerns with substitution?

A: No. Both connectors carry identical REACH Unaffected status, EAR99 ECCN classification, and UL94 V-0 flammability rating. Regulatory compliance is maintained.

Q: What is the impact of different termination methods?

A: The HLEM10R-1RLF uses kinked pins for through-hole insertion; the 0039532104 uses solder termination. Assembly equipment and process parameters must be adjusted accordingly. Electrical performance and reliability are equivalent.

Q: Is the Molex 0039532104 available in production quantities?

A: Yes. The part is actively manufactured and maintained by Molex with active product status, ensuring consistent availability and supply chain support.
