Equivalent & Substitute Parts for SPA02B-15

Part Overview

The SPA02B-15 from MEAN WELL USA Inc. is an isolated module DC-DC converter featuring a single 15V output at 133mA from an 18V–36V input range, supplying 2W output power. The converter is packaged in an 8-SIP module (7 leads), with through-hole mounting, and includes features such as remote on/off, overcurrent protection (OCP), and short circuit protection (SCP). The part is currently obsolete, necessitating the identification and selection of alternative or equivalent models for continued design-in, maintenance, or replacement purposes.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the SPA02B-15 is based strictly on matching the following electrical and mechanical parameters: output voltage (15V), output current (≥133mA), input voltage range, power output (2W), isolation voltage (≥1kV), number of outputs (1), efficiency, package/case (8-SIP Module, 7 Leads), mounting type (through hole), and regulatory compliance (RoHS3, MSL 1, REACH). Only parts that meet or exceed these criteria under the provided specifications are considered as substitutes or equivalents in this product category.

Key parameters for substitution:

• Output voltage and output current
• Input voltage range
• Output power
• Isolation voltage
• Mounting type and package form factor
• Regulatory and safety compliance

Parameter Comparison

Engineering Selection Recommendations

SPA02B-15 is classified as obsolete. Replacement parts such as SPAN02B-15 and RS-1215S/H3 offer compliance with RoHS3, MSL 1, and REACH where specified. SPA02B-15, SPAN02B-15, and RS-1215S/H3 all meet the requirements for through-hole mounting and 8-SIP module, maintaining form factor compatibility. SPA02B-15 and SPAN02B-15 share identical input voltage ranges (18V – 36V); RS-1215S/H3 features an alternate input range (9V – 18V). Output voltage and output current are effectively equivalent among all candidates. Substitution may proceed if environmental and regulatory compliance align with the application’s requirements.

Frequently Asked Questions (FAQ)

Q1: What are the critical parameters when choosing a substitute for SPA02B-15?
A1: Critical parameters include output voltage, output current, input voltage range, output power, isolation voltage, mounting type, package/case, and compliance with RoHS and REACH.

Q2: Are all listed substitutes pin-compatible with SPA02B-15?
A2: All substitutes utilize the 8-SIP Module, 7 leads, supporting compatibility in standard through-hole applications.

Q3: Can RS-1215S/H3 be used directly in place of SPA02B-15?
A3: RS-1215S/H3 offers matching output voltage and current but has a different input voltage range (9V – 18V versus 18V – 36V for SPA02B-15). Substitution is determined strictly by the system’s input voltage.

Q4: How does regulatory compliance affect substitution?
A4: Only parts with documented RoHS3 and REACH compliance, as indicated in the provided parameters, are included as substitutes.

Q5: Is the package size consistent among substitutes?
A5: All substitutes have identical dimensions (0.86" L x 0.36" W x 0.44" H), supporting mechanical interchangeability.

Q6: Do all substitutes have the same operating temperature range?
A6: SPA02B-15 and RS-1215S/H3 specify an operating range of -40°C to 85°C; data for SPAN02B-15 was not provided.
