Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HLE-120-02-S-DV is determined by the following critical parameters:

• Connector Type & Position Count: Must be receptacle or header configuration with 40 positions to maintain PCB footprint compatibility
• Pitch & Row Spacing: 0.100" (2.54mm) pitch and 0.100" (2.54mm) row spacing are mandatory for mechanical interchangeability
• Mounting Type: Surface mount configuration required for assembly process compatibility
• Board-to-Board Style: Maintains the intended application interface
• Solder Termination: Ensures compatibility with standard PCB assembly processes
• Push-Pull Fastening: Provides consistent mating/unmating mechanism
• Current & Voltage Ratings: Substitute must meet or exceed 4.1A per contact and 400VAC specifications
• Operating Temperature Range: Must support -55°C ~ 125°C minimum
• Compliance: ROHS3 compliance required for regulatory alignment

The NPTC202KFMS-RC qualifies as a substitute based on matching pitch, position count, row spacing, mounting type, termination method, and fastening type. Differences in contact finish material, insulation height, and current/voltage ratings are noted in the parameter comparison.

Engineering Selection Recommendations

Selection between HLE-120-02-S-DV and NPTC202KFMS-RC must account for the following factors based on provided specifications:

HLE-120-02-S-DV is the primary choice when:

• Applications require 400VAC voltage rating (substitute rated 250V)
• Current per contact must reach 4.1A (substitute rated 3A)
• Operating temperature minimum of -55°C is required (substitute minimum -40°C)
• Gold contact finish is specified for corrosion resistance or signal integrity
• Beryllium copper contact material is required for performance characteristics

NPTC202KFMS-RC is acceptable when:

• Application voltage does not exceed 250V
• Current per contact requirement is 3A or less
• Operating temperature range of -40°C to 125°C is sufficient
• Tin contact finish meets application requirements
• Phosphor bronze contact material is compatible with the design
• Both parts are ROHS3 compliant and carry MSL 1 rating, ensuring equivalent moisture sensitivity handling

Both connectors maintain identical mechanical compatibility through matching pitch, position count, row spacing, and mounting configuration.

Frequently Asked Questions (FAQ)

Q: Can NPTC202KFMS-RC directly replace HLE-120-02-S-DV in all applications?

A: Direct replacement is limited by electrical specifications. The NPTC202KFMS-RC is rated for 250V and 3A per contact, while the HLE-120-02-S-DV supports 400VAC and 4.1A per contact. Substitution is valid only when application requirements do not exceed the lower electrical ratings of the NPTC202KFMS-RC.

Q: What is the impact of the different insulation heights (0.144" vs 0.299")?

A: Insulation height affects the overall connector profile and mated stacking height. The NPTC202KFMS-RC has a taller insulation profile. PCB layout and clearance requirements must be verified to ensure the substitute does not create mechanical interference in the assembly.

Q: Are the contact materials interchangeable?

A: Both beryllium copper (HLE-120-02-S-DV) and phosphor bronze (NPTC202KFMS-RC) are standard connector contact materials. Material selection depends on application-specific requirements for spring force, wear resistance, and signal characteristics. Verify compatibility with mating contact materials in your system.

Q: Does the operating temperature difference affect substitution?

A: The HLE-120-02-S-DV operates from -55°C to 125°C, while NPTC202KFMS-RC operates from -40°C to 125°C. Substitution is valid only if your application does not require operation below -40°C.

Q: What is the significance of gold versus tin contact finish?

A: Gold plating (HLE-120-02-S-DV) provides superior corrosion resistance and is preferred for high-reliability applications. Tin finish (NPTC202KFMS-RC) is cost-effective and suitable for standard industrial applications. Contact finish selection depends on environmental exposure and signal integrity requirements.

Q: Are both parts equally available?

A: HLE-120-02-S-DV has 880 pcs in stock, while NPTC202KFMS-RC has 52,647 pcs in stock. Availability may influence substitution decisions for high-volume production or urgent requirements.

Q: Do both connectors have the same compliance certifications?

A: Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. Compliance requirements are equivalent for regulatory purposes.
