Substitute Part Grouping Explanation
Substitution eligibility for the SSR10VS-17048 is determined by the following critical parameters:
Primary Matching Criteria:
- Number of Lines: 2 (all substitutes must maintain 2-line configuration)
- Mounting Type: Through Hole (vertical orientation, 4 PC pin package)
- Voltage Rating - AC: 250V (minimum requirement)
- Operating Temperature Range: -25°C minimum and 120°C maximum or better
- Current Rating (Max): 1.7A or higher
- DC Resistance (DCR): 170 mOhm or lower (lower DCR preferred for reduced losses)
Secondary Variation Parameters:
- Inductance @ 10 kHz: Range 1.9 mH to 12.5 mH (application-dependent selection)
- Physical Dimensions: Variations permitted within through-hole footprint compatibility
- Series Designation: SSR, SSHB10H, SSHB10HS series acceptable
Substitutes are grouped into two categories:
Category A - Direct Inductance Equivalents (4.6 mH to 5.8 mH): Parts with inductance values within ±20% of the primary part (4.8 mH), suitable for applications with strict inductance tolerance requirements.
Category B - Functional Equivalents (1.9 mH to 12.5 mH): Parts with inductance values outside the ±20% range but meeting all electrical and mechanical requirements, suitable for applications where inductance variation is acceptable within design specifications.

Engineering Selection Recommendations
For Direct Inductance Substitution (±20% tolerance acceptable):
SSHB10HS-R17046 and SSR10V-17058 are the primary candidates. Both maintain 1.7A current rating and 170-180 mOhm DCR within acceptable range. SSR10V-17058 preserves the original footprint dimensions (23.50mm x 13.00mm), minimizing PCB layout modifications. SSHB10HS-R17046 offers reduced height (15.50mm vs 21.00mm) with slightly lower DCR (170 mOhm), suitable for space-constrained applications.
For Applications Permitting Inductance Variation:
SSHB10H-R17055 (5.5 mH) provides inductance closest to the primary part with improved temperature range (-25°C to 120°C maintained). SSR10H-17058 offers identical electrical specifications to SSR10V-17058 with reduced height profile (13.50mm).
For Higher Current Capacity Requirements:
SSR21NHS-M20103 and SSR21NVS-M20103 support 2.0A current rating with 10.3 mH inductance and superior DCR (150 mOhm). These parts accommodate applications requiring increased current headroom while maintaining 250V AC voltage rating and -25°C to 120°C operating range.
Compliance Verification:
All substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the primary part's regulatory standing. All parts are classified as Active product status with through-hole mounting configuration and vertical 4 PC pin package orientation.
Inventory Availability:
SSR10V-17058 (1377 Pcs), SSR21NVS-M18125 (1351 Pcs), and SSR21NV-M20125 (1298 Pcs) demonstrate highest stock levels, supporting rapid procurement timelines.
Frequently Asked Questions (FAQ)
Q1: Can SSHB10H series parts directly replace SSR10VS-17048 without PCB modification?
A: SSHB10H series parts maintain 2-line through-hole configuration with vertical 4 PC pin package. However, physical dimensions differ: SSHB10H parts measure 22.00mm x 17.00mm with 15.50mm height versus SSR10VS-17048 at 23.50mm x 13.00mm with 21.00mm height. PCB footprint verification is required before substitution.
Q2: What is the significance of DCR (DC Resistance) variation among substitute parts?
A: DCR directly impacts power dissipation and thermal performance. SSR10VS-17048 specifies 170 mOhm maximum. Substitutes with higher DCR (190 mOhm) generate increased heat; those with lower DCR (150 mOhm) reduce losses. Selection depends on thermal budget and efficiency requirements of the application circuit.
Q3: Are SSR21 series parts (2.0A rating) suitable replacements for 1.7A applications?
A: SSR21 series parts with 2.0A rating exceed the primary part's 1.7A specification, providing current margin. However, higher inductance values (10.3 mH to 12.5 mH) and larger physical dimensions (22.00mm x 16.00mm to 23.00mm x 23.00mm) may affect circuit performance and PCB layout. Application-specific validation is required.
Q4: What is the impact of operating temperature range differences?
A: SSR10VS-17048 operates -25°C to 120°C. SSHB10H-17023 extends to -25°C to 130°C, providing 10°C additional high-temperature margin. This difference is significant only for applications operating near thermal limits. Standard industrial applications (-25°C to 120°C) show no functional difference.
Q5: How do inductance variations affect circuit performance?
A: Inductance determines filtering characteristics and impedance at operating frequency. SSR10VS-17048 specifies 4.8 mH @ 10 kHz. Substitutes range from 1.9 mH to 12.5 mH. Applications with strict inductance tolerance requirements must select parts within ±20% (3.84 mH to 5.76 mH range). Applications with flexible inductance specifications may use any listed substitute meeting current and voltage requirements.
Q6: Is footprint compatibility guaranteed for all substitute parts?
A: No. While all parts maintain through-hole mounting with vertical 4 PC pin configuration, physical dimensions vary significantly. SSR10V-17058 matches original footprint (23.50mm x 13.00mm). SSHB10H and SSHB10HS series use different dimensions (22.00mm x 17.00mm). PCB layout review is mandatory before substitution.
Q7: Do all substitute parts maintain ROHS3 and REACH compliance?
A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, matching SSR10VS-17048 regulatory status. No compliance degradation occurs with any listed substitute.
Q8: Which substitute offers the best balance of availability and electrical compatibility?
A: SSR10V-17058 combines highest inventory (1377 Pcs), identical footprint dimensions, matching current rating (1.7A), and inductance within ±20% tolerance (5.8 mH vs 4.8 mH). This part requires no PCB modification and maintains all electrical specifications.
