Amphenol ICC 75844-802-20LF Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 75844-802-20LF is an active rectangular connector header designed for through-hole mounting applications. This vertical 20-position connector operates within the -65°C to 130°C temperature range and is classified as a BERGSTIK® series breakaway header with unshrouded design. The part is RoHS Compliant and carries Moisture Sensitivity Level 1 (Unlimited), making it suitable for standard PCB assembly environments. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in board-to-board or cable connection applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 75844-802-20LF is determined by strict alignment of the following electrical and mechanical parameters:

• Connector positioning and pitch: 20-position, 2-row configuration with 0.100" (2.54mm) mating pitch and row spacing
• Contact geometry: Male pin contacts with square shape
• Mounting and termination: Through-hole solder termination with push-pull fastening
• Shrouding and style: Unshrouded, board-to-board or cable connection capability
• Compliance and environmental ratings: UL94 V-0 flammability rating, MSL 1 (Unlimited), and RoHS compliance status

The Samtec Inc. HTSW-110-07-G-D meets these core substitution criteria. Both parts share identical pitch, position count, row configuration, contact type, mounting method, and compliance certifications. Variations in insulation material (Thermoplastic versus Liquid Crystal Polymer), contact finish thickness, and operating temperature range do not preclude functional substitution when these differences are acceptable within the application context.

Parameter Comparison

Engineering Selection Recommendations

Both the 75844-802-20LF and HTSW-110-07-G-D are active products with current manufacturing status. Selection between these parts is based on the following engineering considerations:

75844-802-20LF (Amphenol ICC): Offers extended operating temperature range (-65°C to 130°C) and RoHS Compliant status. The BERGSTIK® series designation and GXT™ gold finish provide established performance in legacy and new designs. Current inventory: 792 pieces.

HTSW-110-07-G-D (Samtec Inc.): Provides ROHS3 Compliant certification with Liquid Crystal Polymer insulation material, which offers superior dimensional stability and thermal performance compared to thermoplastic. Operating temperature range is -55°C to 125°C. Current inventory: 2253 pieces.

Both parts meet UL94 V-0 flammability requirements and MSL 1 (Unlimited) moisture sensitivity classification. The choice between these substitutes depends on application-specific temperature requirements, insulation material preferences, and compliance certification needs.

Frequently Asked Questions (FAQ)

Q: Can the HTSW-110-07-G-D replace the 75844-802-20LF in all applications?

A: Functional substitution is possible when the application operating temperature remains within the HTSW-110-07-G-D range of -55°C to 125°C. The 75844-802-20LF supports extended low-temperature operation to -65°C. Verify application temperature requirements before substitution.

Q: What are the key differences between these two connector headers?

A: The primary differences are insulation material (Thermoplastic versus Liquid Crystal Polymer), operating temperature range, and RoHS certification level. Both maintain identical electrical and mechanical specifications for pitch, position count, contact type, and mounting method.

Q: Are the physical dimensions compatible for PCB mounting?

A: Both connectors share identical mating pitch (0.100" / 2.54mm), row spacing (0.100" / 2.54mm), and through-hole mounting configuration. PCB footprints are compatible. Minor differences exist in overall contact length (75844-802-20LF: 0.465" / 11.81mm versus HTSW-110-07-G-D: 0.430" / 10.92mm), which may affect mating depth with corresponding receptacles.

Q: Do both parts meet the same compliance standards?

A: Both parts are UL94 V-0 rated and carry MSL 1 (Unlimited) classification. The 75844-802-20LF is RoHS Compliant, while the HTSW-110-07-G-D is ROHS3 Compliant. Both are EAR99 classified and share the same HTSUS code (8536.69.4040).

Q: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: ROHS3 represents the current RoHS Directive 2011/65/EU implementation with updated substance restrictions. RoHS Compliant indicates compliance with earlier RoHS standards. Both certifications restrict hazardous substances; ROHS3 is the more recent standard.

Q: Which part should be selected for new designs?

A: Selection depends on application temperature range and insulation material requirements. For applications requiring extended low-temperature operation below -55°C, the 75844-802-20LF is required. For standard temperature range applications, either part is suitable based on material and certification preferences.
