Key Parameters

Substitute Part Grouping Explanation

Substitution of the SSHB21HS-R20071 is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Number of Lines: 2 (all substitutes must maintain 2-line configuration)
• Mounting Type: Through Hole (all substitutes must be through-hole mounted)
• Package / Case: Vertical, 4 PC Pin (all substitutes must use identical pin configuration)
• Voltage Rating - AC: 250V (all substitutes must meet or exceed this rating)
• Operating Temperature Range: Minimum -25°C to 120°C (all substitutes must cover this range)
• RoHS Status: ROHS3 Compliant (all substitutes must maintain compliance)

Electrical Performance Parameters:

• Inductance @ 10 kHz: Substitutes may vary within application tolerance
• Current Rating (Max): Substitutes must equal or exceed 2A
• DC Resistance (Max): Substitutes must equal or be lower than 140 mOhm

All identified substitute parts meet these mandatory criteria while maintaining active product status and ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active product status and ROHS3 compliance, ensuring regulatory alignment with the original SSHB21HS-R20071. Selection among substitutes depends on specific inductance and current requirements within the application circuit.

SSHB10H-22014 provides the lowest inductance value (1.4 mH) with improved current capacity (2.2A) and reduced DC resistance (120 mOhm). This part extends the operating temperature range to 130°C.

SSHB10H-R22034 offers moderate inductance (3.4 mH) with equivalent current capacity (2.2A) and reduced DC resistance (120 mOhm), maintaining the standard 120°C upper temperature limit.

SSR21NHS-M20103 and SSR21NVS-M20103 both provide higher inductance (10.3 mH) with slightly elevated DC resistance (150 mOhm) while maintaining the 2A current rating and standard temperature range.

SSR21NV-M20125 delivers the highest inductance value (12.5 mH) with the highest DC resistance (160 mOhm) among substitutes, maintaining 2A current capacity and standard temperature range.

All substitutes maintain the 250V AC voltage rating, 2-line configuration, through-hole mounting, and vertical 4-pin package format required for direct mechanical and electrical compatibility.

Frequently Asked Questions (FAQ)

Q: Can SSHB10H-22014 replace SSHB21HS-R20071 in all applications?

A: SSHB10H-22014 is mechanically compatible (through-hole, vertical 4-pin package) and electrically compliant (250V AC, 2-line configuration). However, its inductance value (1.4 mH) differs significantly from the original (7.1 mH). Substitution is valid only when the application circuit tolerates this inductance change. The improved current capacity (2.2A vs 2A) and reduced DC resistance (120 mOhm vs 140 mOhm) provide performance benefits in current-limited designs.

Q: What is the difference between SSR21NHS-M20103 and SSR21NVS-M20103?

A: Both parts share identical electrical specifications: 10.3 mH inductance, 2A current rating, and 150 mOhm DC resistance. The primary difference lies in physical dimensions. SSR21NHS-M20103 measures 0.906" L x 0.906" W (23.00mm x 23.00mm) with 0.571" height (14.50mm), while SSR21NVS-M20103 measures 0.866" L x 0.630" W (22.00mm x 16.00mm) with 1.063" height (27.00mm). Selection depends on available PCB space and mounting orientation constraints.

Q: Does SSR21NV-M20125 provide better filtering than the original part?

A: SSR21NV-M20125 offers higher inductance (12.5 mH vs 7.1 mH), which increases common mode attenuation at the operating frequency. This higher inductance value results in improved filtering performance. However, the elevated DC resistance (160 mOhm vs 140 mOhm) introduces slightly higher power dissipation. Substitution is appropriate when enhanced filtering is required and the additional resistive loss is acceptable within thermal design constraints.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed carry ROHS3 compliance certification, matching the original SSHB21HS-R20071. This ensures regulatory alignment for applications subject to ROHS3 requirements.

Q: Can SSHB10H-R22034 operate at temperatures above 120°C?

A: SSHB10H-R22034 is rated for operation between -25°C and 120°C, identical to the original part. Applications requiring operation above 120°C must use SSHB10H-22014, which extends the upper temperature limit to 130°C.

Q: What is the significance of the 4 PC Pin package configuration?

A: The vertical 4-pin package indicates a standard through-hole common mode choke with two input pins and two output pins, configured for vertical PCB mounting. All substitute parts maintain this identical pin configuration, ensuring direct mechanical compatibility without PCB layout modifications.
